Using Oracle® for natural language document retrieval an automatic query reformulation approach
Jens Grivolla · 2005
In corporate applications, vast amounts of data are often stored in database systems such as Oracle. Apart from structured information this can include text documents which cannot easily be retrieved using traditional SQL queries.Oracle includes means to deal with full text document retrieval (called Oracle Text) that offer special query operators for searches inside text fields. We have explored the effect of these different operators for queries derived from natural language queries. This article compares the retrieval performances achieved with different automatic reformulations from natural language to Oracle SQL queries.
